Unblock Website Through Our Productive Service
Websites can be blocked for many different reasons. Sometimes an Internet Service Provider (ISP) may block certain content for security reasons, or a country may have certain geographical restrictions (also called “geo-blocking”) that it imposes on its citizens. Whatever the case may be, a VPN can be used to unblock website restrictions.
Websites can be blocked at three different levels:
- The computer level
- The network level
- The ISP/government level
Some DNS services will allow their usefrs to block websites from others on the network, and the same process can happen on a grander scale. The government of a particular country may restrict content from its citizens, and it can happen for a number or reasons. A VPN can be useful in this scenario, because it can give you access to these websites. It comes into play if you do a lot of global travel, especially if you’re in China and other parts of Asia.
Using a VPN to Unblock Website Restrictions
Also called a “Virtual Private Network,” a VPN uses end-to-end encryption to block any unauthorized access to information being transmitted between two points on a network. You can use it to add more security to your Internet connection, and it can be used to protect your online privacy. A VPN can prevent any hacking or online surveillance, because it creates a “secure tunnel” through which information can travel.
A VPN can also be used to unblock website restrictions that may be imposed by an ISP or a country in which you’re currently staying. It can divert your location, so you can appear to be accessing the Internet from a different part of the world.
Benefits of End-to-End Encryption
End-to-end encryption allows a network to establish a more secure connection through which information can travel, and anyone who wants access must have a “decryption key.”
It’s an effective way to add more security to a remote-access or site-to-site connection, and many businesses use this technology to allow their employees to access their servers while they are at home or on the go. The same type of encryption method can be used to unblock website restrictions that you may come across if you’re traveling to certain parts of the world.
Common VPN Protocols
The purpose of a VPN protocol is to facilitate the encapsulation and encryption of any data that moves between different points on a network. Many of them use the Point-to-Point Protocol (PPP) to establish the tunnel of communication, and it is where the process usually takes place. That’s why they are often called “tunneling protocols,” as it creates a secure conduit through which data can travel.
There are many different types of VPN protocols, but there are a few that are commonly used.
Point-to-Point Tunneling Protocol (PPTP)
This protocol uses an “IP header” to encrypt and encapsulate any data that moves from one end of the network to the other, and it can be used for both site-to-site and point-to-point VPN connections. The tunnel of communication is established through a PPTP-enabled server, where one end is on the Internet and the other is on a private network (such as a corporate intranet).
The tunnel is managed by the Transfer Control Protocol (TCP), and it uses “IP datagrams” to encapsulate and encrypt certain PPP frames.
Layer 2 Tunneling Protocol (L2TP)
Created by Cisco Systems, this protocol uses both PPTP and Layer 2 Forwarding (L2F) to encapsulate and encrypt any data that moves through the network. The advantage of L2TP is that it takes the best elements of both technologies and puts it in one protocol.
It uses Internet Protocol Security (IPSec) to add an extra layer of protection at the Transport Level. This combination is often called L2TP/IPSec, and it’s what makes the protocol a more robust alternative to PPTP. However, L2TP must be supported by both the client and the server, but it is supported natively by most Windows systems.
Secure Socket Tunneling Protocol (SSTP)
This is a newer technology that uses the HTTPS protocol to facilitate the encapsulation and encryption of data moving through the network. The advantage of this protocol is that it can get past certain firewalls and web proxies that have been known to block PPTP and L2TP traffic.
The data is encapsulated with the Secure Socket Layer (SSL) channel of the HTTPS protocol, which allows the VPN server to use stronger authentication methods that allow for better key negotiation, encryption, and integrity checking.
SSTP uses Port 443 of the TCP protocol, which is where the tunnel of communication is managed. It’s also where the encapsulation and encryption processes take place.
Using a VPN Provider to Unblock Website Restrictions
The purpose of a VPN provider is to offer the benefits of end-to-end encryption without having to go through the hassle of setting it up yourself. It can give you an easy way to add extra security to your Internet connection, and it can be accessed from anywhere.
If you’re traveling abroad, you can use a VPN to unblock website restrictions that may be in place by the country you’re currently visiting.
This is especially true if you’re in certain parts of Asia. Even if you’re not traveling across the world, a VPN can still be useful in keeping your computer safe from hacking or online theft, especially when you’re accessing an open network (like a Wi-Fi hotspot at a hotel or coffee shop).
